问题 I am seeing "Unavailable" message in TestFLight Beta App in iOS8. Please find the attached screenshot, please tell me how to fix this issue. 回答1: I get this all the time. In iTunes Connect, remove yourself as a tester, save, add yourself back, save, then open the beta build through the new invitation email you receive. 回答2: Make sure that the same version (i.e 2.4.1) your'e testing was not approved to sale. When a version is approved for sale by Apple, it becomes unavailable for testing.

问题 When I try to scroll all the way to the bottom of a table view when my view first appears, it doesn't scroll to the correct bottom cell. It's somewhere close to the end but not quite. If the method is called again later, it then scrolls to the bottom. For now my solution was to scroll twice, and it only works if there's a delay on the second one. I'm wondering if this is a bug in iOS 8 or if there's anything I can actually do the proper way. NSIndexPath* path = [NSIndexPath indexPathForRow:

问题 I am trying to create a simple Today Extension. I was able to add a label wherein the value can be updated via the main app. Now, I am exploring the possibility to update the value in main app via the extension.

问题 Does the iPhone 6 have some new way (off-screen/hard button) to reopen a hidden soft keyboard? I don't have a physical device to test with, but I'm seeing something new in the iPhone 6 simulator that I don't see in iPad or iPhone 5. The iPhone 6, in landscape view, now has a "hide keyboard" button, like only iPad has had before.
